skip and take in RxJS
RxJS interview exercise on Filtering, difficulty 1 of 3. Solve it in the editor beside a worked example; the tests run the moment you do.
Write secondAndThird(source$): emit only the second and third values, then complete, whether or not the source ever completes.
Each exercise pairs a worked example with a twin problem to solve in a real editor; the tests run the moment you do. Progress is saved in your browser, and in your account if you sign in.
